DRAW-BAR STOP FOR RAILROAD-CARS.

SPECIFICATION forming part of Letters Patent No. 412,843, dated October 15, 1889..

Application filed July 27, 1889. Serial No. 318,893. (No model.)

To all whom it may concern: 7

Be it known that I, GEORGE IV. CUSHING, of Omaha, in the county of Douglas and State of Nebraska, have invented a certain new and useful Improvement in Draw-Bar Stops for Railroad-Oars, of which improvement the following is a specification.

The object of my invention is to obviate the liability to accident and the expense and delays of repairs resultant upon the injurious strains exerted on draft-timbers by heavy pulls and butting-shocks in handling long trains by large and powerful engines, which detrimental result is mainly due to weakness and imperfection of the ordinary draft apparatu s, and particularly those members through which the strains of draft and buffing are transmitted to the framing of the car.

To this end my invention, generally stated, consists in an integral front and back drawbar stop provided with an upper draw-bar guide, strengthening-ribs, bolt-lugs, and crossbrace, and a draft-timber tenon forming the inner wall of a draw-bar pocket. The improvement claimed is hereinafter fully set forth.

In the accompanying drawings, Figure 1 is a side view,'in elevation, of a draw-bar stop embodying my invention; Fig. 2, a view, half in plan and half in horizontal section, of a pair of said stops as applied to the draft-timbers. of a car 5 and Fig. 3, a vertical transverse section through the same on the line 00 x of Fig. 2.

In the construction heretofore ordinarily employed, so far as my knowledge and information extend, the front and back draw-bar stops are formed of separate blocks, which are independently secured to the draft-timbers, and are connected by draw-bar guides of wrought-iron. Such constructions have been found defective and insufficient, the bolts soon becoming loosened and the draft-timbers split up and destroyed by the concentration of strain upon the separate stops.

In the practice of my invention I provide a draw-bar stop which is formed of an integral plate or body 1, having a front stop or abutment 2, and a back stop 3 at the opposite ends of a draw-bar pocket or recess 4:, against which stops the follower-plates of the drawbar are adapted to abut in draft and buffing respectively. The draw-bar stops are secured to the draft-timbers 5 by bolts 6 passing through holes in the body 1, in front and in rear of the front and back stops 2 and 3,the distribution of shocks throughout the length of the body 1 being thus such as to equalize and reduce, as far as may be, the strain upon the connected portions of the draft-timbers, thereby correspondingly preventing the destructive action thereon before referred to.

In order to .relieve the strain upon the connecting-bolts 6, I form upon the rear of the body 1 a tenon or projection 7, which fits into a corresponding mortise or recess in the drafttimber 5 and forms the inner wall of the drawbar pocket 4. The topof said pocket forms the upper draw-bar guide 8, thus dispensing with the separate guide heretofore employed, the lower draw-bar guide 9 being secured to the bottom of the pocket by bolts 10 passing vertically through the body. Horizontal strengthening-ribs 12 and 13 are formed upon the upper and lower sides of the body 1, the lower rib being provided with front and rear lugs 14 15, for the reception of vertical bolts 16 17, which act as additional connections of, the draw-bar stop to the draft-timber. The opposite draw-bar stops are connected one to the other by across-brace 18, which is secured to the stops by the bolts 17 passing through the rear lugs 15. W

The construction of my improved draw-bar stop is simple and inexpensive, and such that it may be applied in substitution of the ordinary stop, whenever desired, without variation of the general plan or alteration of other members of the draft apparatus. The advantages of strength, reduction of number of parts, and distribution and reduction of local strain have been found in practical service to be of substantial benefit in obviating the undue and premature deterioration of the draftt-imbers heretofore experienced.

I claim as my invention and desire to secure by Letters Patent 1. A draw-bar stop having an integral plate or body, a draw-bar pocket provided with front and back stops or abutments at its opposite ends, holes for draft-timber bolts in front and in rear of said stops, and a tenon or projection formed on the side of the plate which abuts against the draft-ti1nber and eonstitutorbody,adraw-barpoeket provided with front 10 ing theinner wall of the draw-bar pocket, and back stops or abutments at its opposite substantially as set forth. ends, holes for draft-timber bolts in front and 2.
